The Back It Up is a unique vibrating plug and ring combination. The two powerful motors work together in the shaft and base for sensational and complete stimulation. The adjustable arms offer three different positions, while the bulbous plug tapers with a secure base to keep it perfectly in place. The material is ultra-soft silicone and can be used with a water-based lubricant. Thanks to the wireless remote control, you can enjoy ten delightful vibration modes and patterns hands-free, which can only be controlled together. The Back It Up comes with a magnetic USB cable and a wireless remote control with a CR2032 battery. The design is waterproof and can be cleaned with lukewarm water and a toy cleaner.
